WIRE-STRETCHING DEVICE.

Specification of Letters Patent.

Patented Jan. 16, 1912.

Application filed May 5, 1911. Serial No. 625,206.

To all whom @'15 may concern Be it known that I, WILLIAM 00MB, a citizenof the United States, residing at Pebworth, in the county of Owsley andState of Kentucky, have invented new and useful Improvements inWire-Stretching Devices, of which the following is a specification.

An object of the invent-ion a device for stretching wire retain the samein tension.

To accomplish the desired result, use is made of a plurality of hooksprovided with pulleys, one of the hooks having a cord secured thereto,.the said cord passing over a pulley block and over the pulley mountedon the hook having the end of the cord attached thereto, the said cordthen passing over the pulley of the other hooked member and having theend of the cord attached to the mentioned pulley block and a handlesecured to the cord between the hooks.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is a sideelevation. Fig. 2 is a plan view. Fig. 3 is a sectional view through thepulley block. Fig. 4 is a plan view' of a blank from which the hooksarel fashioned.

Referring more particularly .to the views I provide hooks 10, 11 havingpulleys 12, 13 rotatably mounted thereon and the hook 10 is providedwith a plurality of registering apertures 14 through which isA extendedthe end of a cord 15, the said end being secured to the hook 10. Thecord 15 is first passed over a pulley 16 of a pulley block 17 and thesaid cord is then passed over the pulley 12 after which the cord ispassed over the pulley 13 of the hook 11 and the other end of the cordis secured to an eye 18 pivotally mounted on the pulley block 17.Conveniently secured to the cord 15 between the hooks 10, 11 is a handle19. The hook 10 is preferably formed'of a blank 2O having an extension21 adapted to form the hooked portion 22 of the hook 10 and providedwith similar extensions 23 adapted to be bent so that the apertures 24therein will register and mounted in the apertures is the pulley l2, theapertures 14 being also adapted to register as shown in Fig. 1 andhaving the 15 passed therethrough. The hook 11 is made of a blanksimilar to is to provide to releasably A. I-IoL- the blank 2O with theexception that the apertures 14 are omitted and the pulley 13 isjournaled on the hook 11 as has been heretofore mentioned. The pulleyblock 17 consists preferably of an integral piece of material bent in aU-shaped form and having the pulley 16 revolubly mounted thereon,

opening through which is extended the eye 18, the inner end of the eyebeing enlarged so that the same will be retained on the pulley block andwill be pivotally mounted relatively thereto.

In the use of my device, when it is desired to relatively stretch theends of wires so as to move the same toward each other, an end of one ofthe wires is secured to the hook 10 and an' end of the other wire issecured to the hook 11. Now assuming that the pulley block 17 is in aposition adjacent the hook 10 and the handle 19 is in a position.adjacent the hook 11, my device will be extended to it-s fullest lengthas will be readily understood. After the wires have been secured to thehooks as mentioned, the handle 19 is grasped and moved toward the hook10, so that the pulley block 17 will move toward the hook 11, thustending to shorten the distance between the hooks 10 and 11 in that thecord owing to the movement of the pulley block toward the hook 11.

I-Iaving thus fully described the invention, what I claim as new, is z-I 1. A device of the class described comprising a hook, a pulley mountedthereon, a

l block, a pulley mounted on the said block,

a cord secured to the said hook and extending over the pulley on thesaid block, the said cord being then passed over the pulley on the saidhook, a second hook, and a pulley mounted on the second hook and havingthe cord passed thereover, the said cord being then secured to the saidblock.

2. A device of the class described comprising a hook, a pulley mountedthereon, a block, a pulley mounted on the said block, a cord secured tothe said hook and extending over the pulley on the said block, the saidcord being then passed over the pulley on the said hook, a second hook,a pulley mounted on the second hook and having the cord passedthereover, the said cord being then secured to the said block, and ahandle selplurd to the said cord between the said oo s.

the said pulley block being provided with anv will be doubled up 3. Adevice of the class described comprising a plurality of hooks, a cordsecured to one of the hooks, a block, a pulley mounted on the said blockand having the cord passed thereover, pulleys mounted on the said hooks,the said cord being passed over the pulley on the hook having the end ofthe cord secured thereto and the said cord being t-hen passed over thepulley on the other said hook, andan eye pivotally mounted on the saidblock and having the other end of the said cord secured thereto.

4. A device of the class described comprising a plurality of hooks, acord secured to one of the hooks, a block, a pulley mounted. on the saidblock and having the cord passed thereover, pulleys mounted 0n the saidhooks, the said cord being passed over the pulley on the hook having theend of the cord secured thereto and the said cord being said cord beingthen successively passed over the pulleys 0n the attaching members withthe other end of the said cord secured to the said block.

In testimony whereof I ailiX in presence of two Witnesses.

WILLIAM A. HOLCOMB. Iitnesses my signature then passed over the pulleyon the other E. E. Hoes, said hook, an eye pivotally mounted on the P.M. FRYE.
